CLOSING DEVICE FOR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 526,329, datedSeptember 18, 1894.

Application iiled July 6. 1893. Serial No. 479,745. (No model.)

To all whom it may concern:

Be it known that I, AUGUST WILHELM SCHROEDTER, a subject of the King ofPrussia, German Emperor, and a resident of Berlin, in the Kingdom 0fPrussia, German Empire, have invented certain new and usefulImprovements in Closing Devices for Bottles, of which the following isan exact specilcation.

My invention relates to that kind of closing-devices for bottles, inwhich the former is constantly connected with the latter, and in whichthe closing-cap proper is, or lmay be, connected at both sides with aring or ring-like part encircling the neck of the bottle, and thenovelty in this case consists in a special arrangement of hinges andcombination of parts as willhereinafter be more fully described.

In order to make my meaning more clear, I refer to the accompanyingdrawings, in which- Figure 1 is a side-view of my new device, shown inproper connection with a bottle, and closing the same. Fig. 2 is also aside view of the same part, the device being opened and the rnain partof the bottle being left off. Fig. 3 is an upper view of the parts asshown in Fig. 2, the neck of the bottle being in section. Fig. 4 is afront view of my stopper.

Similar letters refer to similar parts throughout the different views.

The ring a by means of which the whole device is held in its openedpositiony as well as in its closed one has in its middle part an ear o.and at both ends angular pieces a2 a2 which may be drawn toward eachother by a screw b as much as `necessary to press ring a thereby into agroove c provided on the neck d of the bottle d. There is then a spaceleft between the parts 0.2 a2 as to be seen in Fig. 3. A cross-piece chaving at one side a projection e with ear e2, and at the other side anear e3 is connected by means of link fV with the ring a. Saidcross-piece e holds the closing-cap proper g by means of screw h, theangular head h of which latter is surrounded by a small tube i fixed tothe upper side of cross-piece e. Cap g is guided at one side by a pin gsecured to the cap, and eX- tending into a suitable slot of projectione.

Now the main part of my invention consists in the arrangement of theflap k lo which by means of its two apertures k2, is connected with eare2 of projection e like a hinge. Part la of said flap forms a handle,part 7c a hook. This hook gripes over the screw or 'pin I) and is keptin that position bya spring Z fixed to the flap lo lo' above ear e2, andpressing against cap c. Now,on putting the cap on the mouth of thebottle, and pressing at the same time on handle lc, hook lo willgripeover pin b, and will be coupled therewith as soon as handle k isreleased. The bottle is closed now preliminarily, and is then tightlyclosed by pressing the cap firmly down on to the mouth of the bottle bymeans of screw h, 't'. e., by a suitable key put on the angular head h'of said screw.

I am well aware, that closing-devices of similar construction have beenmade prior i to my invention. In those older constructions, however, thelast part of the three-fold hinge, c'. e. the ap la k was secured to thering around the neck. Therefore, after having removed the cap from themouth the flap remained in upright position at the side of or lparallelto, the neck, which latter, consequently was not completely free. Thisdraw back has been omitted in my new construc-` I now do not claim aclosing-device of the' type shown broadly; but

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

In a bottle-stopper in which a cross-piece (e) carrying the closing-capproper (g) is movably held from a neck-ring (a) by means of a link (f),the combination with the neckring a having its ends a2 al bent offparallel and connected by a screw or pin b, o f a double-armed lever lt7c hinged to a projection c forming part of cross-piece e, and situatedopposite to link f; arm lo of said lever forming -a'hook adapted tocatch over pin or screw` b, arm 7c forming a handle for operating saidhook; a springladapted to keep hooked arm 7c and pin or screw b inengagement be- TOO ing arranged between arm Za and projection tspecification in the presence of two subscribing witnesses.
